If the bearing hub bore doesn't fitproperly, it calls for replacement of the drum or rotor or hub. In few cases the spindles mightnot be aligned in a straight line; thus, it becomes necessary to carry outproper diagnosis of the problem.In one of the methods used for diagnosing such kind of noise, the vehicle isdriven at a constant speed; slight changes to the speed are occasionally made. 

Working of BearingsA bearing is a machine component whichperforms the function of constraining the relative motion between moving partsof the machine. It must be dealt with or repaired at theearliest.The dangers associated with wheel bearingnoise shouldn't go undetected. Rear Wheel Bearing NoiseNoise produced by the rear and front wheelbearings is almost the same. At the time ofinspection, one should check if there is any damage caused to the bearing hubbore; its fitting should also be checked. In such instances, consulting an expert should be the right thingto do Findout more about belt tensioner Wheel Hubs Suppliers China manufacturer by visit daybec . The parts which bear the hub bore andspindles should also be checked for any kind of damage. The act of constraining the relative motion is aimed atfacilitating only a certain kind of motion (differs from machine to machine).The different types of motions permitted by bearings are linear motion, axialrotation, hinge motion and spherical rotation. To detect theminute cracks, one should diagnose the bearing in bright light. In some cases, it is not possible to find out the problemon our own. Even smaller cracks can later on cause big problems.Front Wheel Bearing NoiseThe front wheel should be checked for noiseas well as lubrication.

It is important that you vary the speed because there are certain cars whichmake noise only at certain speeds. The steering knuckle should be replaced ifthere is any problem in the operation of spindles. Source: Free Articles from ArticlesFactory .At the time of driving, listen carefully toany sound originating from wheels. One should alsocheck whether spindles are aligned properly. While diagnosing the problem of wheelbearing noise, one should check if there are any cracks on the surface of thebearing.

Noise originating from the floorboardindicates that the problem is not related to wheel bearing; in fact, it couldoriginate in any other part of the vehicle.Servicing of the front wheel bearing shouldbe done every 30,000 miles. In such cases, diagnosing the problem associatedwith bearing noise can be difficult
